R840 Server Installation Guidelines; Stack Up For A Minimum Configuration - Dell EMC VxFlex Ready Node Installation Manual

R840 Equipment Installation

R840 server installation guidelines

Minimum and maximum stack up configurations are provided in this topic.
Throughout this document, it is assumed that a 40 U rack is being used. If you plan to use a custom rack, or only part of
a rack, it is highly recommended that a complete analysis is performed in order to ensure that there is enough power
supplied to the nodes. In addition, it is essential that a custom rack has sufficient air flow and heat distribution among
nodes. Therefore, for custom rack configurations, perform an air flow analysis and ensure that there is enough spacing
between nodes.
Ensure that there is at least one redundant power zone available for power connections.
To ensure proper performance and avoid throttling, the R840 server requires the appropriate inlet temperature. Review
this requirement and maintain correct inlet temperature. For more information, see environmental specifications in the
Hardware Replacement and Services Guide .
When systems are installed into an empty rack, always begin component installation at
the bottom of the cabinet and work upward. Install components at the lowest available
space for that component type.
If you are installing the minimum configuration, the stack up will be as follows:
